    A sample of neon gas is contained in the left hand bulb and a sample of helium gas is contained in the right hand bulb of a two bulb container connected by a valve, as shown in the diagram. Initially the valve is closed.The left hand bulb has a volume of 9.00 L, and the Ne gas is at a pressure of 2.00 atm. The right hand bulb has a volume of 3.00L, and the He gas is at a pressure of 4.00 atm. After the valve is opened, what is true about the relative partial pressures of helium and neon? Assume constant temperature.
    • A. 

      The partial pressure of helium is 1.50 times as great as the partial pressure of neon

    • B. 

      The partial pressure of neon is 2.00 times as great as the partial pressure of helium

    • C. 

      The partial pressure of neon is 1.50 times as great as the partial pressure of helium

    • D. 

      The partial pressure of helium is 2.00 times as great as the partial pressure of neon
